Look what I found.

[Britsmoothy]

I thought I was rid of it!
But look what turned up as I checked my powder store.

The useless course powder
I put some calipers on it.

I shot some of it today and yep, it's as useless as before. You have to tip so much of it in before anything happens. Standard loads are worse than a 410! With the measure set on 100gn it starts to sound useful but it's not! Misfires to, useless stuff.
This stuff turns a 12g and contemporary normal loads into a 20yard gun!

Anyway, what do the kernel sizes equate to in the F grades please?

You can make some fireworks.

 

[Zonie]

It won't even work well for fireworks.

It might work real good for blowing stumps out of the ground or dislodging 40 ton boulders from a hillside.

I'm not one who likes the idea of pulverizing powder but in this case, perhaps using a wooden rolling pin and a flat board to "roll out" the powder into smaller pieces might give a useful powder?

That powder isn't that old either. When you can see a website address on the container you know it wasn't made before the web got up and running.

 

[TFoley]

'Course'? WTH?

What is means is ,'course it's bloody-well useless' in a small-bore gun, and by small-bore, I mean 12g.

I'm betting it's intended for 'very large bore shotguns, punt guns and cannon. ' Oh, wait, I just got that off the Krank's website......

Not sure, ff maybe? Good for camp fire pyrotechnics!

Yes this type of powder was mainly for the large bore fowling guns using a standard load it shoot well in a 4 or 6 bore . Over the years I must have used many kilos which in early times was the coarse powder by Cuttiss and Harvey. Used in the proper bores for which it is made is just has good has other powders in smaller bores . Once again people condemned a powder which they nothing about and how it was used has for fireworks powder Ruddyard may well come in with a answer on this powder

I was cleaning out my upstairs closet today, found a couple cans of Goex!

I still have some unopened Curtis & Harvey FFF in tins & plastic bottles, price still on them-- $7

 

[LawrenceA]

Sounds like you need a cannon or punt gun now
Otherwise it will be wasted and that would be bad for the environment.

It still will be OK more suited for smoothbore shotguns from 12 and smaller .

Bill CuRtis will be pretty peeved that you've mispelled the name of his illustrious ancestor....

About 1f. Though the smaller kernel could fall into the 2f range, the larger one is too big. Maybe an oddball like Swiss 1.5f?

Thank you. How do folks use that stuff is beyond me.

I wonder if it will work in the .45 if I tip 80gns in. Hmm, I wonder if the smaller bore will get pressure up sooner.

Yes it is my bad spelling although it is prominent on the tin ,I often do the wrong spelling which I have been told that by Mr Curtis in the past.

He must have unconsciously used the "Southern" pronunciation...

When I was doing the Lewis and Clark bicentennial we had a small swivel gun mounted of the bow of the keel boat. It had a 1 1/2 bore and that's just about the size powder we used in it. You can see the gun mounted on the keel boat below.

I should think not, but you never know.

I tried 80 grains of American 1Fg in a 20 bore (and folks indicate the stuff is close to 1Fg), and the Squirrel that I shot at gave me the two-finger salute before scampering off..., clearly the squirrel was an Anglophile as am I, as he used a British gesture, and not the American equivalent!

Nice picture.

Nice picture.

That was on the Missouri river in the Dakotas. The river becomes more a series of lake then the river Lewis and Clark saw.

If I was given this powder when I started I would of given up and missed out !
